New Guinea Impatiens plant named ‘Fisimp 171’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Fisimp 171’, characterized by its outwardly spreading, rounded and uniformly mounded plant habit; freely branching and freely flowering habit; large rounded cherry red-colored flowers that are positioned above and beyond the foliage; and dark green-colored leaves.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Impatiens hawkeri cultivar Fisimp 171.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the name ‘Fisimp 171’.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Hillscheid, Germany. The objective of the breeding program is to develop new moderately compact Impatiens cultivars that flower relatively early with large rounded flowers and attractive flower colors.

The new Impatiens originated from a cross made by the Inventor in July, 1997 of the Impatiens hawkeri cultivar Kinoc, disclosed in U.S. Plant Pat. No. 10,433, or seed, parent with the Impatiens hawkeri cultivar Conga, not patented, as the male, or pollen, parent. The cultivar Fisimp 171 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Moncarapacho, Portugal in March, 1998.

Asexual reproduction of the new cultivar by terminal cuttings taken in Moncarapacho, Portugal, since March, 1998, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Fisimp 171’. These characteristics in combination distinguish ‘Fisimp 171’ as a new and distinct Impatiens cultivar:

1. Outwardly spreading, rounded and uniformly mounded plant habit.

2. Freely branching and freely flowering habit.

3. Large rounded cherry red-colored flowers that are positioned above and beyond the foliage.

4. Dark green-colored leaves.

Plants of the new Impatiens can be compared to plants of the female parent, the cultivar Kinoc. In side-by-side comparisons conducted by the Inventor in Hillscheid, Germany, plants of the new Impatiens differed from plants of the cultivar Kinoc in the following characteristics:

1. Plants of the new Impatiens had lighter green-colored leaves than plants of the cultivar Kinoc.

2. Flowers of plants of the new Impatiens were cherry red in color whereas flowers of plants of the cultivar Kinoc were red purple in color.

Plants of the new Impatiens can be compared to plants of the male parent, the cultivar Conga. In side-by-side comparisons conducted by the Inventor in Hillscheid, Germany, plants of the new Impatiens differed from plants of the cultivar Conga in the following characteristics:

1. Plants of the new Impatiens had broader leaves than plants of the cultivar Conga.

2. Flowers of plants of the new Impatiens were cherry red in color whereas flowers of plants of the cultivar Conga were dark pink in color.

Plants of the new Impatiens can also be compared to plants of the cultivar Danharcher, not patented. In side-by-side comparisons conducted by the Inventor in Hillscheid, Germany, plants of the new Impatiens differed from plants of the cultivar Danharcher in the following characteristics:

1. Plants of the new Impatiens had narrower and darker green-colored leaves than plants of the cultivar Danharcher.

2. Flowers of plants of the new Impatiens were larger and flatter than flowers of plants of the cultivar Danharcher.

3. Flowers of plants of the new Impatiens were cherry red in color whereas flowers of plants of the cultivar Danharcher were more red purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘Fisimp 171’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Fisimp 171 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photograph, following observations and measurements describe plants grown in Langley, British Columbia, Canada, under commercial practice in a greenhouse. Rooted young plants were planted in 17.5-cm containers during the spring and the aforementioned photograph and following observations and measurements were taken during the summer about 17 weeks later. During the production of the plants, day temperatures ranged from 21 to 24° C. and night temperatures were about 17 to 18° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
